Union filesytem is currently "busted" AFAIK in 4.5. Perhaps Terry Lambert can comment more meaningfully on the cache coherency issue. We're doing work for a commercial project, but hope to return a portion of it to the FreeBSD Project if we can get it committed -- the politics of which are beyond my comprehension ;-) There is also some weirdness, IIRC, to doing union mounts which mix RO and RW filesystems, but I may be misremembering.
